Twenty-four children with conduct disorders were familiarized with a pattern-matching task, and their self-efficacy expectations for this task were assessed. Subjects were then given either “Success” or “Failure” feedback for a series of similar problems, and their self-efficacy was reassessed. Finally, task persistence was evaluated by allowing subjects to attempt as many additional pattern-matching problems as they wished, with all subjects receiving failure feedback. Results indicated that, although the two groups of subjects were initially similar, the success group's self-efficacy was significantly higher following feedback. The success group also attempted significantly more problems while later receiving failure feedback, and there was a significant positive correlation between task persistence and the second self-efficacy rating. These findings were related to Bandura's self-efficacy theory and to educational programming for conduct-disordered children.  相似文献

Traditionally, it has been assumed that during middle-distance running oxygen uptake (VO2) reaches its maximal value (VO2max) providing the event is of a sufficient duration; however, this assumption is largely based on observations in individuals with a relatively low VO2max. The aim of this study was to determine whether VO2max is related to the VO2 attained (i.e. VO2peak) during middle-distance running on a treadmill. Fifteen well-trained male runners (age 23.3 +/- 3.8 years, height 1.80 +/- 0.10 m, body mass 76.9 +/- 10.6 kg) volunteered to participate in the study. The participants undertook two 800-m trials to examine the reproducibility of the VO2 response. These two trials, together with a progressive test to determine VO2max, were completed in a randomized order. Oxygen uptake was determined throughout each test using 15-s Douglas bag collections. Following the application of a 30-s rolling average, the highest VO2 during the progressive test (i.e. VO2max) was compared with the highest VO2 during the 800-m trials (i.e. VO2peak) to examine the relationship between VO2max and the VO2 attained in the 800-m trials. For the 15 runners, VO2max was 58.9 +/- 7.1 ml x kg(-1) x min(-1). Two groups were formed using a median split based on VO2max. For the high and low VO2max groups, VO2max was 65.7 +/- 3.0 and 52.4 +/- 1.8 ml x kg(-1) x min(-1) respectively. The limits of agreement (95%) for test-retest reproducibility for the VO2 attained during the 800-m trials were +/- 3.5 ml x kg(-1) x min(-1) for a VO2peak of 50.6 ml x kg(-1) x min(-1) (the mean VO2peak for the low VO2max group) and +/- 2.3 ml x kg(-1) x min(-1) for a VO2peak of 59.0 ml x kg(-1) x min(-1) (the mean VO2peak for the high VO2max group), with a bias in VO2peak between the 800-m runs (i.e. the mean difference) of 1.2 ml x kg(-1) x min(-1). The VO2peak for the 800-m runs was 54.8 +/- 4.9 ml x kg(-1) x min(-1) for all 15 runners. For the high and low VO2max groups, VO2peak was 59.0 +/- 3.3 ml x kg(-1) x min(-1) (i.e. 90% VO2max) and 50.6 +/- 2.0 ml x kg(-1) x min(-1) (i.e. 97% VO2max) respectively. The negative relationship (-0.77) between VO2max and % VO2max attained for all 15 runners was significant (P = 0.001). These results demonstrate that (i) reproducibility is good and (ii) that VO2max is related to the %VO2max achieved, with participants with a higher VO2max achieving a lower %VO2max in an 800-m trial on a treadmill.  相似文献

The shortage of qualified managers to assign to overseas positions has necessitated rethinking of the viable candidates pools. A relatively new group of global managers have emerged, inpatriate managers. These are foreign nationals and third-country nationals who are relocated to the organization's domestic headquarters to serve as a “linking-pin” to the global marketplace. This paper examines challenges to effectively incorporating these inpatriate managers into the domestic organization. The various issues with inpatriate manager adjustment to the domestic macro and organizational culture are examined. In addition, the necessary social support in work and non-work contexts is discussed.  相似文献

In the late 1950s, a health charity, known as the National Foundation for Infantile Paralysis (March of Dimes), organized American teens into volunteer divisions to fight polio, as well as tame adult anxieties surrounding juvenile delinquency. The alliance that developed permitted the NFIP to increase its influence and revenue, while granting teens an opportunity to assert their cultural power and challenge negative stereotypes. Although the NFIP nurtured and at times dominated the relationship, young volunteers joined for their own reasons and shaped the program to suit their own aspirations and interests.  相似文献

Three controversial issues surrounding the differentiation between the socially maladjusted (SM) and the seriously emotionally disturbed (SED) are examined. The first issue addresses the question whether treatment methods should differ for these two groups. Some have argued that the same treatment methods should be used with both groups, while others advocate that differentiated treatment is necessary if these two groups are to receive an appropriate education. The second issue focuses on whether the SM are truly handicapped. Drawing upon professional opinion, research findings, and rational analysis, it is argued that the socially maladjusted as a group are free from serious emotional disturbance. The third issue pertains to the education of the SM. It is pointed out that many provisions for the SM are already available, although perhaps overlooked. The call for a continuum of services is made.  相似文献
